How This Interaction Works

The interaction between Esmolol Hydrochloride and Epinephrine occurs because vasoconstrictive and positive inotropic effects conflict with beta blockade. Clinically, this means do not use esmolol to control tachycardia in patients receiving epinephrine due to risk of reducing cardiac contractility in presence of high systemic vascular resistance. Because of the severity of this interaction, these medications are contraindicated — meaning they should not be taken together under any circumstances. If you are currently taking both, contact your healthcare provider immediately to discuss alternatives.

What To Tell Your Doctor or Pharmacist

If you are taking Esmolol Hydrochloride and your doctor is considering prescribing Epinephrine (or vice versa), make sure to:

  • Inform your doctor and pharmacist of all current medications, including over-the-counter drugs and supplements
  • Ask whether the benefits of combining these medications outweigh the risks for your specific situation
  • Ask what symptoms to watch for that would indicate the interaction is causing problems
  • Ask about alternative medications that do not interact with your current regimen
  • Ask how frequently you should be monitored while these are co-prescribed
  • Never stop or change either medication without first consulting your healthcare provider
